Answer:
Hi there!
The answer to this question is: 7
Step-by-step explanation:
You simply plug in the values given and solve
8(1/2) + 3(7) -18
4+21-18=7
The given series is

Where the first term, a , is 3.
And the difference is constant, that is

So the constant difference, d is 3.
Since the difference is constant, so the given series is arthmetic.
And for explicit rule, we use the formula of nth term, which is

Substituting the values of a and d, we will get

Recursive rule is used to tell us the relationship between previous and current term. And the required rule is

No, it has a negative slope not a positive
Equilateral Triangle - all sides equal and all angles equal
Isosceles Triangle - two sides equal andtwo angles equal
Scalene Triangle - no sides equal and no angles equal
so
1-6 a)
Isosceles Triangle - 1 Line of Symmetry
1-6b)
Equilateral Triangle- 3 Lines of Symmetry
1-6 c)
